Re: Hyundai L90D+ inverter mosfet problem



Just try this, and it seems that U4 is shorted on P channel. I've got 0v from D to S and S to D, that's it ?

Thanks to ecking767 and dondrusco for your tips guys ! I do not know this ability on Fairchild website ! Unfortunately, it doesn't return me anything with APM9932.

So, a 0.1 uF capacitor for C23 will be good ?...

I recently found a dead 19" Hyundai L90D+ that I really would like to fix and I think I'm getting closer to this.
Here is what's the problem : just after plug in the power cord, the blue power led turns on. About 5 seconds later, this same led quickly turns to orange and everything shutdown like if a short has come (I can also hear a tick at this time). So, this process restart and loop forever. No Backlight at all.

Looking to the power/inverter...
